Connect HSBC to Hypamoon
Possible, with help from HSBC. The API is documented, but you cannot just create a key: access goes through HSBC first.
PossibleThe check
Three questions about the API of HSBC, answered from its own docs.
- Public API docs
- Yes. The HSBC Developer Portal documents Open Banking APIs and, after approval, corporate APIs such as Treasury Account Information and Treasury Payment Initiation. Read the docs
- A key you create yourself
- No. Corporate API access needs approval, and production apps are not registered on the portal; that process starts with the bank. Open Banking production needs regulatory permission. develop.hsbc.com
- Versions or a changelog
- Yes. HSBC publishes API news, and the Open Banking APIs follow the versioned UK Open Banking Standard. develop.hsbc.com
- How it signs in
- OAuth 2.0 and OpenID Connect with certificates from a qualified trust service provider or the Open Banking Directory; corporate APIs use credentials set up by HSBC.
- Webhooks
- Not confirmed.
- Hosting
- Cloud
- Condition
- Corporate APIs need approval and onboarding by HSBC. Without that, read HSBC business accounts through a licensed open banking aggregator such as TrueLayer (https://docs.truelayer.com/docs/data-api-basics).
What you can build
Pull real time balances and transactions of your HSBC accounts into your own app and reconcile them against open invoices, once HSBC has approved corporate API access.
Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work
Good to know
- HSBC signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for HSBC takes more work: ask your chat to check this first.
- HSBC offers Account Information - UK - HSBC Business through Open Banking and treasury APIs for corporate customers, including bulk balance requests.
Try it in your chat
First get access from HSBC. Then fill in what to read and write, and send it.
Build the Hypamoon recipe build-an-adapter for HSBC. API docs: https://develop.hsbc.com/apis. Read: [what]. Write: [what, or nothing].
In Claude, or another chat with the full Hypamoon connection; adapters are not in ChatGPT yet. You paste the key in the portal, never in the chat. The full recipe

Tool not listed? Ask the chat to check its API.
The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
Fill in the name of your software. Checking needs no connection to Hypamoon.
Ready to connect HSBC?
Connect your chat once, then ask it to build the adapter.
